This invention relates to screen structure and particularly to a structure of storm window. As is well known, storm windows are now used in the colder ortions of the country, and one common orm of storm window is a sash which is usually outer si e thereof, and is of a size to cover the entire frame. Such storm windows are customarily put up in the fall and taken down in the spring and it has been the common procedure to place the storm windows in position from the outside ofthe building, the same other fastening means. As the storm windows are used on the upper as well as. the lower storiesLit is quite a task to manipulate the same and osition them properly, es cially if a wind e blowing.

llt is an object of this invention, therefore, to provide a storm window of such structure that the same can( be placed in posiian securely fastened in place yin thel window ame. It is lanother object of the inventiorl to wlndow of such structure placedin position from the building and which also has Ventilating the' building without moving the entire storm window.

It is more specifically an object of the invention to provide a storm window structure comprising upper andlower sash which may be placed in position from the interior 0f the building,

section which `may be swung open to provide that it may be interior of the ventilation.`

These and other objects and advantages of the invention willbe fully set forth in the following description made in connection with the accompanying drawings, in which like reference characters refer to similar part1 throughout the several views and ,in W C Fig. 1 is a view in front elevation as seen from the exterior of the windows;

as indicated by the arrows, certain parts ing shown in different positions in dotted lines Fig. A3 is a horizontal section taken on line 3-3 of Fig. 1, as indicated bythe arrows;

Fig. 4 is a horizontal sectiontaken on a window and (placed in the window frame at the being held by buttons or each of which has a hinged of any desired form,

is a vertical section taken` on liney adapted to enter a keeper 20 line 4 4 of Fig. 1, as indicated bythe ar-4 rows; and Y n Fig. 5 is a partial view similar to Fig. 4,. shown on an enlarged scale. i y

Fig. 6 is a partial vertical section similar to that shown in Fig. 2, illustrating a modication. l

Referring to the drawings, ing or frame 10 of the usual shown, having the Vusual side 'rs and the lower outer sill side sill 10 b -strip 11. The frame is provided at its inner side with the beads or parting strips 10' swhich form'- the usual ideways for the liding upper sash 12 anthe lower sash 13.

In accordance with the present invention, the window frame is provided with grooves or rabbetted strips 14 at thereof, between which extend the top strips 14h and the bottom strips 14". 'The stri s are each provided with the valining rig t angle groove or rabbet 14". A pair of stoxun window sash 15 and 16 are provided, forming respectively the upper and lower sash, and these are constructed and arranged to fit against the strips 14, 14" and 14 andV to lit in the grooves or rabbets 14d. sash 16 at its bottom side is rabbetted at 16l a window casconstruction is and top mem- 10. The inalso shown as to fit within the strip 14.

The frame 16 is shown as having the pointed ridge alongits top surface fitting into a corresponding V-shaped groove in the bottom of the upper sash 15. The sash frames 15 and 16 fit outwardlyafrainst the strips 14, 14" and 14 and are hel from inward movement by catches 17. While these catches may be in the embodiment of the invention illustrated they are shown as comprisin small bearings 17l and boltsvl?" slidable t erein, said bolts having thereon the handle pieces 17". The bolts 17h are adapted to enter holes 10c formed in the side. members of the window casing. The upper sash frame 15 has disposed therein, at its upper end a swingingrsection 15'L connected to a cross bar 15" of said frame by the hinges 18. The section 15'* is held in closed positlon by the small catch member 19 secured to its upper side. While the catch member 19 may be of any desired form, in the/embodiment of the invention illustrated it is shown as of the same type as the catch 17 The bolt member 19l -of the catch 19, however, is carried on the the outer sides,

is shown as is the inside stile i inf, The lower sash top of the frame 15. Suitable means are provided for holding the swinging section 15 in different open positions, and while various means might be used for this purpose, in the embodiment of the invention illustrated, the section 15l is shown as provided with a chain 21 adapted to have various links thereof engaged over a hook 22 secured in the 4upper portion of the frame 15. The section 15i has a glass panel 15c thererame 16 also has the swinging section 16al at its lower portion, pivoted to the cross bar 16b by the hinges 21, said section 16 being adapted to be held in closed position bythe catch member 19 similar to the catch member 19 on the section 15, and which also co-operates with a keeper 20 carried on the lower portion of sash ,frame 16. Suitable means are also provided for holding the swinging section 16* in diierent open positions and while various means might be used for this purpose,

' in the embodiment of the invention illustrated a short chainy 23 is secured to a side of said section adapted to have various links thereof engaged over a hook member 24 carried in the cross bar 161.

The section 16 can be held as stated above, in various open positions, by manipulating the chain 23. The desired ventilation can thus be obtained throu h the lower sash without moving or disturbing the storm window sash frame 16. In like manner, the upper inner sash 12 can be lowered as indicated in dotted lines in Fig. 2 and the section 15 swung inwardly, which section can be held in different positions by manipulating the chain 21. The desired ventilation is thus obtained through the top of the upper sash.

Obviously both the sections 15 and 16 may' be openedl at the same time if desired. It is thus not necessary to disturb or move either of the sash frames 15 or 16 in order to secure ventilation for the frame.

and

By omitting the beveled or grooved arrangement atnthe meeting line of frames 15 16 and making the bottom of frame 16 in one plane as shown in Fig. 6, the sash 16 could be inverted if` desired so that the swinging section 16 would be at the upper4 rtion thereof.

It will be noted that the inner side of the strips 14," 14 and 14 are within the inner lines of the parting strips or beads 10.

When it is desired to place the storm wrindows 15 and 16 in position, the lower sash 13 will 'be raised to its highest position. The sash 16 can then be passed through the opening left by the sash 13 and can be fitted outwardly against theA strips 14 and 14. The catches 17 wi-llthen be moved to 'posi- Y tion to hold the frame 16 in place. The upper sash 12 is then lowered to its -lowest position and the storm window` 15 can then be Ainserted through lthe opening left by this sash. The window 15 is placed downward on top of the window 16 and then moved outwardly against the strips 14:a and 14 and the catches 17 moved to hold the window in place. The storm Windows are now tightl and securely in position and as describe they are positioned without having to work from or at the exterior of the building. When it is desired to ventilate, the lowel sash 13 can be raised and the section 16 swung inwardly as much as desired. Frames similar to frames 15 and 16 could obviously be used to carry screens for use in the summer season, which frames could be positioned similarly to frames 15 and 16.

From the above description it is seen that applicant has provided a very simple and etlicient structure of storm window.' The storm window sash placed in position from the interior of the building and securely held in place. The desired ventilation can be obtained without bodily moving the sash and by a comparatively small opening of the inside sash. The storm windows are easily made and the installation thereof requires very little change in the standard window frame.

'It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out-the objects above set forth, in the novel parts and combinations of arts disclosed and defined in the appende claims.

What is claimed is 1. A storm window structure comprising a two part sash frame, means on the window casing against which said frame abuts, said sash frame extending throughout substantially the whole area of the opening in said casing, means at the inside of said frame for holding the same in position, said frame having a smaller section therein hingedly mounted in each of said parts for free swinging movement.
